Uhm, no? There is barely enough space for Rust, which happens to have a unique feature/value proposition that raises it above the vast majority of its competitors. If you're fine with UB or memory unsafe code, then you go with C simply because its deeply entrenched.

In that sense Zen-C changed too many things at once for no good reason. If it was just C with defer, there would have been an opportunity to include defer in the next release of the C standard.
